Computing a systematized collection of data that can be accessed immediately and manipulated by a data-processing system for a specific purpose

database

An organized collection of related data that is stored in a computer system and is accessed by means of a set of programs known as a database management system. A database may provide data that is available to all users of a computer system and may be shared by a number of different applications. Examples include ESA's EXOSAT Database and NASA's Astrophysics Data System.

database

A set of related files that is created and managed by a database management system (DBMS). Today, most DBMSs can manage any form of data including text, images, sound and video. Database and file structures are always determined by the software. As far as the hardware is concerned, all data are simply "bits and bytes." See DBMS.


Data Are Bits and Bytes
To the hardware, data are nothing more than bits and bytes. The software determines the format of the data and how to handle it. To understand data and file structures, review the hierarchy and terms in this illustration.

Hierarchies are used for nearly all data structures of materials information in existing materials data bases But at some level of detail, they fail to capture some important relationships Also, if the hierarchy is good but only locally true (for instance, if the distinction between crystalline and glassy ceramics is compared to the distinction between thermosetting and thermoplastic polymers), then it can be seen that different semantic interpretations in different parts of the tree could cause problems.
